Opened this issue · 1 comments

Hi, I setup a new ubuntu20.04 vm, run commands in misc/provision.sh to prepare the environment.
Then I try the example with make and FITM_ARGS=config/fitm-args.ftp.json make run, but I got criu dump failed error message. The fuzzer stuck at gen1 for about 1min then exit.
Could you please help? Thank you.

In active-state/snapshot/criu.log, it seems that the snapshot works
